&lt;!-- THREE STEPS TO INSTALL KEYBOARD SLIDER:

  1.  Copy the coding into the HEAD of your HTML document
  2.  Add the onLoad event handler into the BODY tag
  3.  Put the last coding into the BODY of your HTML document  --&gt;

&lt;!-- STEP ONE: Paste this code into the HEAD of your HTML document  --&gt;

&lt;HEAD&gt;

&lt;SCRIPT LANGUAGE="JavaScript"&gt;
&lt;!-- Original:  Massimo Giari (motore@iol.it) --&gt;

&lt;! &gt;
&lt;! &gt;

&lt;!-- Begin
n = (document.layers) ? 1 : 0;
ie = (document.all) ? 1 : 0;
function moveImage() {
if (n) {
block = document.blockDiv;
}
if (ie) {
block = blockDiv.style;
}
block.xpos = parseInt(block.left);
block.active = 0;
document.onkeydown = keyDown;
document.onkeyup = keyUp;
if (n) {
document.captureEvents(Event.keydown | Event.keyup); 
   }
}
function keyDown(e) {
if (n) {
var nKey = e.which;
var ieKey = 0;
}
if (ie) {
var ieKey = event.keyCode;
var nKey = 0;
}
if ((nKey == 97 || ieKey == 65) && !block.active) {   
block.active = 1;
slideLeft();
}
if ((nKey == 100 || ieKey == 68) && !block.active) {   
block.active = 1;

   }
}
function slideLeft() {

block.left = block.xpos;
status = block.xpos;
setTimeout("slideLeft()", 25);
   }
}
//  End --&gt;
&lt;/script&gt;
&lt;/HEAD&gt;

&lt;!-- STEP TWO: Insert the onLoad event handler into your BODY tag  --&gt;

&lt;BODY OnLoad="moveImage()"&gt;

&lt;!-- STEP THREE: Copy this code into the BODY of your HTML document  --&gt;

&lt;! &gt;
&lt;! &gt;

&lt;div id="blockDiv" STYLE="position:absolute; left:317px; top:130px; width:137px; height: 121px"&gt; 
&lt;img src="javaguy.gif" width="115" height="63"&gt;&lt;/div&gt;

Use &lt;b&gt;A&lt;/b&gt; to move the image toward left, &lt;b&gt;D&lt;/b&gt; to move the image right.
